Letters Patent No. 87,311, dated February 23, 1869.

IIVIPROVED THILL-CO'UPLING.

The Schedule referred to in these Letters Patent and making part of the lame.

To all fwhomit may concern Be it known that I, EDWARD J. WATSON, of Bridgeport, in the county of Fairtie ld,- and State of Connecticut, have invented a new Improvement in Carriage- Shackle's; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specilication, and represent, in

Figure 1a side view,

Figure 2, atop view, and in Figure 3, a longitudinal'central section.

This invention relates to an improvement in the means of attaching the shafts or pole to carriages, the

article known to thev trade as'carriage-ShackIeS, thev obj ect being to produce a shackle without bolts or other equivalent removable parts; and

The invention -consists in forming, upn the clip ordevice for attachment to the' axle, two ears, the space between the two', transversely `across the shackle, being formed toreceive the cylindrical end ofthe thill-iron, and so that the said cylindrical end may be turned freely, to' raise or lower the shafts, and the two parts secured together by a set-screw, which holdsthe thilliron in place, while it permits itsfree movement.

To enable others to fully understand my improvement, I will proceed to describe the same as illustrated in the accompanyingdrawngs.

A is the clip, or equivalent means, for attachment. to the axle, having formed thereon two'ears, B and C,

the space between the' two .ears bored or worked out to form a seat for the cylindrical end, D, of the thilliron E, the said end, D, being fitted so'as' to pass transf versely into its seat, orwithdrawn, as denoted in red,

iig-2, and, when inserted into its seat, may be freely raised or lowered, as denoted in iig. 1, the cylindrical part D turning freely in its seat. K

To secure the thill-iron in place, I form, upon the under side of the cylindrical end or head D, a recess,

a, as seen in iig. 3, and through the shackle I place a setscrew, d, which, when the thill-'iron is in proper position, is screwed up into the recess, as denoted in tig. 3, and thus prevent the transverse movement of the thill-iron.l

To remove the shafts or thill-iron, loosen'the setscrew. I I 'am aware of the patent granted to H. R. Hoagland, July ,9, 1867, for thin-attachment, but do not wishlto'be understood as broadly claiming anything embraced in the invention ofthe said Hoagland. In that patent, the transverseslot through one of the cheeks, and the peculiar constructionof the thill-iron,

so as to work in the said transverse slot,are entirelyavoided in the construction, as herein shown and claimed.

Having fully described my invention, y

y What I lclaim as new and useful, and desire to secure by Letters Patent, is

' The herein-described carriage-shackle, afs/an improvedarticle of manufacture, consisting of the thilliron E, constructed with its cylindrical head D, and a corresponding coupling formed by the two ears B and O, and combined with` the set-screw d, substantially as and for the purpose set forth.
